Works great

Lisa from Amarillo, TX– Verified Buyer

We bought this heater to go with a king size duel bladder mattress. It is plenty powerful enough to heat both sides. It was easy to install.

Nice and Warm

Kelly from Kissimmee, FL– Verified Buyer

This product works very well at heating the water and keeping it at a stable temperature. The only downfall is there aren't numbers associated with the settings it is just low, med, & high with in-betweens. Very easy to use and set up. Make sure you use warm to hot water when filling up the bed otherwise it takes a few hours for the heater to reach the correct temperature. Otherwise a great product. It really makes a difference with warm water.

This product is a must have for waterbed

Marilee from Taylorsville, NC– Verified Buyer

We bought this heater for as a replacement for our softside waterbed. It had heated to temperature within two days. We were able to feel its heat within hours. It is very easy to keep the temperature of our mattress regulated with this product. I am very pleased.

Excellent heater.

whirlibird from Holyoke, CO

Excellent heater, easy to set up and keeps the temperature steady. More than worth the cost.

The only complaint is the lack of temperature numbers on the control, but despite that I'd get another tomorrow if needed.

Good product

from Alabama– Verified Buyer

Product works as advertised. Thermostat is a dial setting 1-10 (think), and not marked by temperature.


"I would buy this product again

Softside heater works great in Hardside

BedBug from FL– Verified Buyer

No problems. I chose the lower wattage heater for use in our Hardside bed. We're in FL so there's no need for a high wattage unit. Thermostat controls it accurately.
